L2PT Functional Requirements
For L2PT to function properly, QinQ must be enabled on the switch (see
“Enabling QinQ Tunneling on the Switch), and the interface configured to
802.1Q uplink mode (see Adding an Interface to a QinQ Tunnel”).
Configuring the
L2PT Tunnel Address
Use the VLAN > L2PT (Configure Global) page to configure the destination MAC
address for Layer 2 Protocol Tunneling.
Parameters
These parameters are displayed:
Tunnel MAC Address – The switch rewrites the destination MAC address in all
upstream L2PT protocol packets (e.g., STP BPDUs) to this value, and forwards them
on to uplink ports. (Format xx-xx-xx-xx-xx-xx or xxxxxxxxxxxx; Default: 01-12-CF-
.00-00-02, proprietary tunnel address)
Web Interface
To configure the destination MAC address for L2PT:
1. Click VLAN, L2PT.
2. Select Configure Global from the Step list.
3. Set the tunnel MAC address.
